Roll out sculpee into a sheet about 1/8th an inch thick.
Use a template (like a mug) to cut out each coaster.
Add a pattern around the edge of the coaster. I used the end of a clothespin.
Create a splattered pattern by flicking a paint-soaked toothbrush. Paint brush works too!
Bake at 275 degrees Fahrenheit for 15 minutes.
Let cool, then use! Optional: Add felt to the bottom for extra protection against the coaster slipping on the table.
